Q345D carbon steel plate sheet heavy plate boiler steel

Smelting process of Q345D carbon steel plate sheet, container plate SPA-H weather-resistant steel: The molten iron for smelting SPA-H steel must be pretreated by molten iron desulfurization. Before entering the converter, the sulfur content of the molten iron is ≤0.010%, and the slag on the surface of the molten iron is cleaned. Nickel plates, copper particles or nickel-copper alloys are added to the converter with scrap steel. The carbon content of the converter smelting end is required to be less than 0.06% to prevent the molten steel from being oxidized.

The large diameter cold drawn seamless steel pipe is a steel pipe with an outer diameter of more than 1000mm. The large diameter seamless steel pipe is made of steel ingot or solid billet through perforation and then hot rolling, cold rolling or cold drawing. If they are long, they need to remove the redundant parts, that is, cut them out. Their length Q345D carbon steel plate sheet is suitable for the length required by the construction of steel pipes.
